Before beginning treatment, all participants will undergo medical imaging using the VISIA CA, QuantifiCare imaging system or similar non-invasive visual system. Additionally, their skin will be assessed for transepidermal water loss, wrinkle depth and elasticity (non invasive procedures). Optionally, skin will be tested using non-invasive methods for skin color, hydration, sebum content and will be evaluated using ultrasound scanner (DeremaLab Combo or similar).
